Assume a thermal efficiency is 32%, power 1000 mwe, uranium is $521b. u308 $145 kgswu, conversion is $11/kgu, losses in conversion 0.15%, product enrichment of 4.7wt%, tails assay of 0.23 wt%, reference core contains 85 tonne fuel, capacity factor is 0.92. an average economical grade of uranium ore is 0.2%. the average fuel discharge burnup is 50,000 mwd/mtu for the referenced reactor core, what is the requirement of natural uranium, swu, and ore to provide the . swu is riched uranium for the reactor fuel for a typical reload of one-third of the core? what is the cost of the fuel required for the batch reload? what is the optimal tails assay to minimize the cost of the enriched uranium (not necessarily the value given above and used in your analysis here)? plot (using excel or similar) the cost of enriched fuel vs. tails assay and include in your exam. clearly outline the methodology (formulae) used in your calculation to produce the plot. for the batch of fuel in problem 4, what is the energy requirement (input) for the enrichment process if produced using gas centrifuge? recompute for gaseous diffusion. provide your answers for the entire batch of fuel as well as per kg u (fuel). what are typical values of energy requirements per unit separative work unit (kgswu) for gas centrifuge and gaseous diffusion methods?
